TB871: Archetype 3 — Limits to growth
Note: this is a post reflecting on one of the modules of my MSc in Systems Thinking in Practice. You can see all of the related posts in this category.
The third archetype introduced in the module materials (Activity 2.24) is ‘limits to growth’ where trying harder stops working after a while:
This archetype takes its name from the book by Donella Meadows and her colleagues (Meadows et al., 1972). It consists of a reinforcing loop and a balancing loop running side-by-side… It is a formalisation of the observation that success breeds success.
Growth breeds growth initially, but, as time moves forward, it becomes harder and harder to sustain.
[…]
Initial effort is rewarded with good performance that elicits further effort. Eventually, it is impossible to make more effort, or it is impossible to improve the performance further. A limit to growth has been reached, often stopping the reinforcing loop quite suddenly.
This archetype often manifests itself when the just-try-harder approach no longer works. It becomes impossible, for example, to reduce hospital-acquired infection rates any further simply by cleaning ‘deeper’ and more frequently; there is a level of infection that is part of the human condition and impossible to eradicate without isolating patients in ways that impair their recovery. Universities may become better at delivering education with less money, but at some point the level of reduction would mean that students get completely inadequate modules and support.

As in any context, there’s only so much more you can do with less. For example, in a library context, if you cut the budget and staff try harder to come up with new ways of increasing visitor numbers and improving provision, eventually this takes its toll.
